In Islamic culture, geometric design is everywhere: you can find it in mosques, madrasas, palaces, and private homes. And despite the remarkable complexity of these designs, they can be created with just a compass to draw circles and a ruler to make lines within them. Eric Broug covers the basics of geometric Islamic design.

Islamic for sure, because it includes arabic and spanish influences as well. So it is a blend of all the influences that could be got in the then islamic world.

The weather temperatures in Maryland follows the sin and cos with respect to the length of the day (sin) and the temperatures (cos). They are 45 days out of phase. Meaning, on Dec 21, the shortest day does not produce the coldest days, which happen in February 10th. Same holds for Summer solstice which is June 21, while hottest temps are August 10th region. In Maryland, Valentines Day is the bottom of winter, or the beginning of the end of winter and is true for all latitudes similar to Maryland.

This is joke on mathematics. I, however, like mathematical jokes.
